Abstract
The landscape ecology approach is an important way to study ecological security. Mountainous area is ecologically an important green defense and water source in regional areas. The significance of studying mountainous landscape ecology and environmental security is beyond words and it will be vitally important to recover the integrality of ecosystem and to deal with ecological environment. This paper is based on the remote sensing image data of 1987 and 2000, from the perspective of protecting biodiversities and ecological environment to determine the source of the study focus, and then a Minimum Cumulative Resistance (MCR) surface model has been developed using ArcGIS 9.0 and ERDAS 8.6 to establish the Minimum Cumulative Resistance surface. By analyzing landscape minimum cumulative resistance surface and the relationship between resistance value and area, the buffer area used to study ecological security can be determined, and thus determining inter-source linkage, radiating channels and strategic point. Landscape ecology security pattern can be differentiated by spatial analysis and ecology security region can be divided into high security zone, moderate security zone and low security zone. Barycenter transfer model is applied to analyze the spatial and temporal change of landscape security pattern. The result statistics indicated three points: (1)The bound of high security zone has been reduced 381.9149 km2, with an average of 29.3781 km2 per year, and the barycenter transferred to north-west about 2.07 km; (2)The bound of moderate security zone has been increased 60.5418 km2, with an average of 4.6571 km2 per year, and the barycenter transferred to north-west about 3.99 km; (3)The bound of low security zone has increased 321.3731 km2, with an average of 24.7210 km2 per year, and the barycenter transferred to north-west about 2.07 km. The reasons are as followed: although the voice to protect ecological environment has been shouted up and up and the government indeed has made greater efforts to protect our environment, the rapid economic development is continuing making the plundering of resources and environmental pollution even seriously in the western mountainous area.
